Chapter 10 Homo vs heterogeneous; dominant vs recessive Homologous chromosomes carry the same kinds of genes for the same characteristics Genes for the same characteristic are found at the same loci on both homologous chromosomes Each cell carries two alleles per characteristic, one on each of the two homologous chromosomes If both homologous chromosomes carry the same allele (gene form) at a given gene locus, the organism is homozygous at that locus . When two different alleles are present in an organism (heterozygous), a dominant allele may mask a recessive allele, even though the recessive allele is

Unformatted text preview: still present Ex: In edible peas the purple-flower trait is dominant to the white-flower trait (purple allele + white allele = purple flower) Genotype vs phenotype The particular combination of the two alleles carried by an individual is called the genotype (what you have ) The physical expression of the genotype is known as the phenotype (what you show ) Ex. Purple flowers (Dominant: P) + White flowers (recessive: p) = Purple flowers Genotype = Pp (Purple; White) Phenotype = Purple flowers Mendel:success,5 principles of genetics...
